The Lowdown
Alright folks, Rusty here. Gotta be straight with you on this one – the outlook for Kohala Lighthouse is a tough read. The whole 16-day window is a write-off for decent paddle surfing. We’re looking at a solid run of onshore and cross-shore winds from the ENE that just won't let up, mixing up the water something shocking. There's a bit of swell in the water, but the conditions are just messy with a capital M.
The water temp is sitting at a warm 80.2°, which is about average for this time of year, so at least you won't freeze while you're getting chopped up.
The first few days of August are a no-go. Monday the 3rd through to the 5th have waist-high swell around 4.3ft to 4.6ft, but it's coming from the ENE with a short fetch and the wind is blowing hard from the same direction, making for proper choppy, blown-out conditions. The energy is weak to moderate (between 283 and 473), and the wave comment says it all: “poor surf conditions.” Tuesday the 4th sees the period stretch to 11 seconds, suggesting a bit more push, but the wind is still on it, ruining any chance of a clean face.
From Thursday the 6th all the way through to the end of the window on the 18th, the swell actually builds. We start seeing 5.2ft to 7.9ft on offer, with the combined energy jumping into strong territory (racking up to 910 by the 16th). But the wind stays locked in from the ENE, blowing at 19 to 25 mph, keeping it a lumpy, cross-choppy mess. The wave comment stays brutally consistent: “poor surf conditions.” For a spot that needs clean conditions, we just aren't getting them. With this much wind and that kind of bumpy swell, this setup looks way more interesting for kite surfing than paddle surfing.
Bottom line: there’s absolutely nothing to recommend here in this 16-day window. The wind pattern is the enemy, plain and simple. Keep the board in the rack, or look for a completely sheltered spot. Forecasts can always change, but this run looks stubborn.
